2.3 LevelSender Batteries

A LevelSender uses three 1.5V AA replaceable lithium batteries to operate. Batteries need to be installed before programming.


Alkaline batteries can also be used, but battery life estimates will be reduced. They may also reduce the operating temperature range.


2.3.1 Installing LevelSender Batteries

To install the batteries:

  1. Unscrew the stainless steel cap from the LevelSender to access the battery compartment.
  2. Install the three batteries with the positive ends first/down, in the battery compartment.
  3. Replace the stainless steel cap.


If you are not using your LevelSender for more than two months, Solinst recommends removing the batteries for long term storage.

Every 15 Minutes Every Hour 2 Months 1.8 Months

Table 2-2 LevelSender Battery Life Estimates



Estimates are based on three 1.5V AA lithium batteries.


The LevelSender will use battery power each time it samples, reports, and checks for updates. As such, more frequent intervals will drain the battery more quickly.
